Some Smith and Wesson revolvers come from the factory with a rough double action trigger pull. It's an easy job to smooth it up however if you know the process. In this video Larry Potterfield, CEO and Founder of MidwayUSA, details how to smooth the double action pull using just a couple of hand tools. He starts by removing the trigger and the hammer from the revolver. The double action surface on the trigger is stoned using a fine India stone and a steel bench block. He then removes the double action sear surface from the hammer and polishes the surface with the stone. Once all of the areas have been touched up the gun is reassembled and function tested.
